// constructor:
	/**
	 * EventDispatcher provides methods for managing queues of event listeners and dispatching events.
	 *
	 * You can either extend EventDispatcher or mix its methods into an existing prototype or instance by using the
	 * EventDispatcher {{#crossLink "EventDispatcher/initialize"}}{{/crossLink}} method.
	 * 
	 * Together with the CreateJS Event class, EventDispatcher provides an extended event model that is based on the
	 * DOM Level 2 event model, including addEventListener, removeEventListener, and dispatchEvent. It supports
	 * bubbling / capture, preventDefault, stopPropagation, stopImmediatePropagation, and handleEvent.
	 * 
	 * EventDispatcher also exposes a {{#crossLink "EventDispatcher/on"}}{{/crossLink}} method, which makes it easier
	 * to create scoped listeners, listeners that only run once, and listeners with associated arbitrary data. The 
	 * {{#crossLink "EventDispatcher/off"}}{{/crossLink}} method is merely an alias to
	 * {{#crossLink "EventDispatcher/removeEventListener"}}{{/crossLink}}.
	 * 
	 * Another addition to the DOM Level 2 model is the {{#crossLink "EventDispatcher/removeAllEventListeners"}}{{/crossLink}}
	 * method, which can be used to listeners for all events, or listeners for a specific event. The Event object also 
	 * includes a {{#crossLink "Event/remove"}}{{/crossLink}} method which removes the active listener.
	 *
	 * <h4>Example</h4>
	 * Add EventDispatcher capabilities to the "MyClass" class.
	 *
	 *      EventDispatcher.initialize(MyClass.prototype);
	 *
	 * Add an event (see {{#crossLink "EventDispatcher/addEventListener"}}{{/crossLink}}).
	 *
	 *      instance.addEventListener("eventName", handlerMethod);
	 *      function handlerMethod(event) {
	 *          console.log(event.target + " Was Clicked");
	 *      }
	 *
	 * <b>Maintaining proper scope</b><br />
	 * Scope (ie. "this") can be be a challenge with events. Using the {{#crossLink "EventDispatcher/on"}}{{/crossLink}}
	 * method to subscribe to events simplifies this.
	 *
	 *      instance.addEventListener("click", function(event) {
	 *          console.log(instance == this); // false, scope is ambiguous.
	 *      });
	 *      
	 *      instance.on("click", function(event) {
	 *          console.log(instance == this); // true, "on" uses dispatcher scope by default.
	 *      });
	 * 
	 * If you want to use addEventListener instead, you may want to use function.bind() or a similar proxy to manage
	 * scope.
	 *
	 * <b>Browser support</b>
	 * The event model in CreateJS can be used separately from the suite in any project, however the inheritance model
	 * requires modern browsers (IE9+).

(function() {

// constructor:
	/**
	 * Encapsulates the properties and methods associated with a sprite sheet. A sprite sheet is a series of images (usually
	 * animation frames) combined into a larger image (or images). For example, an animation consisting of eight 100x100
	 * images could be combined into a single 400x200 sprite sheet (4 frames across by 2 high).
	 *
	 * The data passed to the SpriteSheet constructor defines:
	 * <ol>
	 * 	<li> The source image or images to use.</li>
	 * 	<li> The positions of individual image frames.</li>
	 * 	<li> Sequences of frames that form named animations. Optional.</li>
	 * 	<li> The target playback framerate. Optional.</li>
	 * </ol>
	 * <h3>SpriteSheet Format</h3>
	 * SpriteSheets are an object with two required properties (`images` and `frames`), and two optional properties
	 * (`framerate` and `animations`). This makes them easy to define in javascript code, or in JSON.
	 *
	 * <h4>images</h4>
	 * An array of source images. Images can be either an HTMlimage
	 * instance, or a uri to an image. The former is recommended to control preloading.
	 *
	 * 	images: [image1, "path/to/image2.png"],
	 *
	 * <h4>frames</h4>
	 * Defines the individual frames. There are two supported formats for frame data:
	 * When all of the frames are the same size (in a grid), use an object with `width`, `height`, `regX`, `regY`,
	 * and `count` properties.
	 *
	 * <ul>
	 *  <li>`width` & `height` are required and specify the dimensions of the frames</li>
	 *  <li>`regX` & `regY` indicate the registration point or "origin" of the frames</li>
	 *  <li>`spacing` indicate the spacing between frames</li>
	 *  <li>`margin` specify the margin around the image(s)</li>
	 *  <li>`count` allows you to specify the total number of frames in the spritesheet; if omitted, this will
	 *  be calculated based on the dimensions of the source images and the frames. Frames will be assigned
	 *  indexes based on their position in the source images (left to right, top to bottom).</li>
	 * </ul>
	 *
	 *  	frames: {width:64, height:64, count:20, regX: 32, regY:64, spacing:0, margin:0}
	 *
	 * If the frames are of different sizes, use an array of frame definitions. Each definition is itself an array
	 * with 4 required and 3 optional entries, in the order:
	 *
	 * <ul>
	 *  <li>The first four, `x`, `y`, `width`, and `height` are required and define the frame rectangle.</li>
	 *  <li>The fifth, `imageIndex`, specifies the index of the source image (defaults to 0)</li>
	 *  <li>The last two, `regX` and `regY` specify the registration point of the frame</li>
	 * </ul>
	 *
	 * 	frames: [
	 * 		// x, y, width, height, imageIndex*, regX*, regY*
	 * 		[64, 0, 96, 64],
	 * 		[0, 0, 64, 64, 1, 32, 32]
	 * 		// etc.
	 * 	]
	 *
	 * <h4>animations</h4>
	 * Optional. An object defining sequences of frames to play as named animations. Each property corresponds to an
	 * animation of the same name. Each animation must specify the frames to play, and may
	 * also include a relative playback `speed` (ex. 2 would playback at double speed, 0.5 at half), and
	 * the name of the `next` animation to sequence to after it completes.
	 *
	 * There are three formats supported for defining the frames in an animation, which can be mixed and matched as appropriate:
	 * <ol>
	 * 	<li>for a single frame animation, you can simply specify the frame index
	 *
	 * 		animations: {
	 * 			sit: 7
	 * 		}
	 *
	 * </li>
	 * <li>
	 *      for an animation of consecutive frames, you can use an array with two required, and two optional entries
	 * 		in the order: `start`, `end`, `next`, and `speed`. This will play the frames from start to end inclusive.
	 *
	 * 		animations: {
	 * 			// start, end, next*, speed*
	 * 			run: [0, 8],
	 * 			jump: [9, 12, "run", 2]
	 * 		}
	 *
	 *  </li>
	 *  <li>
	 *     for non-consecutive frames, you can use an object with a `frames` property defining an array of frame
	 *     indexes to play in order. The object can also specify `next` and `speed` properties.
	 *
	 * 		animations: {
	 * 			walk: {
	 * 				frames: [1,2,3,3,2,1]
	 * 			},
	 * 			shoot: {
	 * 				frames: [1,4,5,6],
	 * 				next: "walk",
	 * 				speed: 0.5
	 * 			}
	 * 		}
	 *
	 *  </li>
	 * </ol>
	 * <strong>Note:</strong> the `speed` property was added in EaselJS 0.7.0. Earlier versions had a `frequency`
	 * property instead, which was the inverse of `speed`. For example, a value of "4" would be 1/4 normal speed in
	 * earlier versions, but is 4x normal speed in EaselJS 0.7.0+.
	 *
	 * <h4>framerate</h4>
	 * Optional. Indicates the default framerate to play this spritesheet at in frames per second. See
	 * {{#crossLink "SpriteSheet/framerate:property"}}{{/crossLink}} for more information.
	 *
	 * 		framerate: 20
	 *
	 * Note that the Sprite framerate will only work if the stage update method is provided with the {{#crossLink "Ticker/tick:event"}}{{/crossLink}}
	 * event generated by the {{#crossLink "Ticker"}}{{/crossLink}}.
	 *
	 * 		createjs.Ticker.on("tick", handleTick);
	 * 		function handleTick(event) {
	 *			stage.update(event);
	 *		}
	 *
	 * <h3>Example</h3>
	 * To define a simple sprite sheet, with a single image "sprites.jpg" arranged in a regular 50x50 grid with three
	 * animations: "stand" showing the first frame, "run" looping frame 1-5 inclusive, and "jump" playing frame 6-8 and
	 * sequencing back to run.
	 *
	 * 		var data = {
	 * 			images: ["sprites.jpg"],
	 * 			frames: {width:50, height:50},
	 * 			animations: {
	 * 				stand:0,
	 * 				run:[1,5],
	 * 				jump:[6,8,"run"]
	 * 			}
	 * 		};
	 * 		var spriteSheet = new createjs.SpriteSheet(data);
	 * 		var animation = new createjs.Sprite(spriteSheet, "run");
	 *
	 * <h3>Generating SpriteSheet Images</h3>
	 * Spritesheets can be created manually by combining images in PhotoShop, and specifying the frame size or
	 * coordinates manually, however there are a number of tools that facilitate this.
	 * <ul>
	 *     <li>Exporting SpriteSheets or HTML5 content from Flash Pro supports the EaselJS SpriteSheet format.</li>
	 *     <li>The popular <a href="https://www.codeandweb.com/texturepacker/easeljs" target="_blank">Texture Packer</a> has
	 *     EaselJS support.
	 *     <li>SWF animations in Flash can be exported to SpriteSheets using <a href="http://createjs.com/zoe" target="_blank"></a></li>
	 * </ul>
	 *
	 * <h3>Cross Origin Issues</h3>
	 * <strong>Warning:</strong> Images loaded cross-origin will throw cross-origin security errors when interacted with
	 * using:
	 * <ul>
	 *     <li>a mouse</li>
	 *     <li>methods such as {{#crossLink "Container/getObjectUnderPoint"}}{{/crossLink}}</li>
	 *     <li>Filters (see {{#crossLink "Filter"}}{{/crossLink}})</li>
	 *     <li>caching (see {{#crossLink "DisplayObject/cache"}}{{/crossLink}})</li>
	 * </ul>
	 * You can get around this by setting `crossOrigin` property on your images before passing them to EaselJS, or
	 * setting the `crossOrigin` property on PreloadJS' LoadQueue or LoadItems.
	 *
	 * 		var image = new Image();
	 * 		img.crossOrigin="Anonymous";
	 * 		img.src = "http://server-with-CORS-support.com/path/to/image.jpg";
	 *
	 * If you pass string paths to SpriteSheets, they will not work cross-origin. The server that stores the image must
	 * support cross-origin requests, or this will not work. For more information, check out
	 * <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS" target="_blank">CORS overview on MDN</a>.

	/**
	 * The Graphics class exposes an easy to use API for generating vector drawing instructions and drawing them to a
	 * specified context. Note that you can use Graphics without any dependency on the EaselJS framework by calling {{#crossLink "Graphics/draw"}}{{/crossLink}}
	 * directly, or it can be used with the {{#crossLink "Shape"}}{{/crossLink}} object to draw vector graphics within the
	 * context of an EaselJS display list.
	 *
	 * There are two approaches to working with Graphics object: calling methods on a Graphics instance (the "Graphics API"), or
	 * instantiating Graphics command objects and adding them to the graphics queue via {{#crossLink "Graphics/append"}}{{/crossLink}}.
	 * The former abstracts the latter, simplifying beginning and ending paths, fills, and strokes.
	 *
	 *      var g = new createjs.Graphics();
	 *      g.setStrokeStyle(1);
	 *      g.beginStroke("#000000");
	 *      g.beginFill("red");
	 *      g.drawCircle(0,0,30);
	 *
	 * All drawing methods in Graphics return the Graphics instance, so they can be chained together. For example,
	 * the following line of code would generate the instructions to draw a rectangle with a red stroke and blue fill:
	 *
	 *      myGraphics.beginStroke("red").beginFill("blue").drawRect(20, 20, 100, 50);
	 *
	 * Each graphics API call generates a command object (see below). The last command to be created can be accessed via
	 * {{#crossLink "Graphics/command:property"}}{{/crossLink}}:
	 *
	 *      var fillCommand = myGraphics.beginFill("red").command;
	 *      // ... later, update the fill style/color:
	 *      fillCommand.style = "blue";
	 *      // or change it to a bitmap fill:
	 *      fillCommand.bitmap(myImage);
	 *
	 * For more direct control of rendering, you can instantiate and append command objects to the graphics queue directly. In this case, you
	 * need to manage path creation manually, and ensure that fill/stroke is applied to a defined path:
	 *
	 *      // start a new path. Graphics.beginCmd is a reusable BeginPath instance:
	 *      myGraphics.append(createjs.Graphics.beginCmd);
	 *      // we need to define the path before applying the fill:
	 *      var circle = new createjs.Graphics.Circle(0,0,30);
	 *      myGraphics.append(circle);
	 *      // fill the path we just defined:
	 *      var fill = new createjs.Graphics.Fill("red");
	 *      myGraphics.append(fill);
	 *
	 * These approaches can be used together, for example to insert a custom command:
	 *
	 *      myGraphics.beginFill("red");
	 *      var customCommand = new CustomSpiralCommand(etc);
	 *      myGraphics.append(customCommand);
	 *      myGraphics.beginFill("blue");
	 *      myGraphics.drawCircle(0, 0, 30);
	 *
	 * See {{#crossLink "Graphics/append"}}{{/crossLink}} for more info on creating custom commands.
	 *
	 * <h4>Tiny API</h4>
	 * The Graphics class also includes a "tiny API", which is one or two-letter methods that are shortcuts for all of the
	 * Graphics methods. These methods are great for creating compact instructions, and is used by the Toolkit for CreateJS
	 * to generate readable code. All tiny methods are marked as protected, so you can view them by enabling protected
	 * descriptions in the docs.

	/**
	 * Stores all graphics commands so they won't be executed in future draws. Calling store() a second time adds to
	 * the existing store. This also affects `drawAsPath()`.
	 *
	 * This is useful in cases where you are creating vector graphics in an iterative manner (ex. generative art), so
	 * that only new graphics need to be drawn (which can provide huge performance benefits), but you wish to retain all
	 * of the vector instructions for later use (ex. scaling, modifying, or exporting).
	 *
	 * Note that calling store() will force the active path (if any) to be ended in a manner similar to changing
	 * the fill or stroke.
	 *
	 * For example, consider a application where the user draws lines with the mouse. As each line segment (or collection of
	 * segments) are added to a Shape, it can be rasterized using {{#crossLink "DisplayObject/updateCache"}}{{/crossLink}},
	 * and then stored, so that it can be redrawn at a different scale when the application is resized, or exported to SVG.
	 *
	 * 	// set up cache:
	 * 	myShape.cache(0,0,500,500,scale);
	 *
	 * 	// when the user drags, draw a new line:
	 * 	myShape.graphics.moveTo(oldX,oldY).lineTo(newX,newY);
	 * 	// then draw it into the existing cache:
	 * 	myShape.updateCache("source-over");
	 * 	// store the new line, so it isn't redrawn next time:
	 * 	myShape.store();
	 *
	 * 	// then, when the window resizes, we can re-render at a different scale:
	 * 	// first, unstore all our lines:
	 * 	myShape.unstore();
	 * 	// then cache using the new scale:
	 * 	myShape.cache(0,0,500,500,newScale);

	 * Draws the display object into a new canvas, which is then used for subsequent draws. For complex content
	 * that does not change frequently (ex. a Container with many children that do not move, or a complex vector Shape),
	 * this can provide for much faster rendering because the content does not need to be re-rendered each tick. The
	 * cached display object can be moved, rotated, faded, etc freely, however if its content changes, you must
	 * manually update the cache by calling <code>updateCache()</code> or <code>cache()</code> again. You must specify
	 * the cache area via the x, y, w, and h parameters. This defines the rectangle that will be rendered and cached
	 * using this display object's coordinates.
	 *
	 * <h4>Example</h4>
	 * For example if you defined a Shape that drew a circle at 0, 0 with a radius of 25:
	 *
	 *      var shape = new createjs.Shape();
	 *      shape.graphics.beginFill("#ff0000").drawCircle(0, 0, 25);
	 *      myShape.cache(-25, -25, 50, 50);
	 *
	 * Note that filters need to be defined <em>before</em> the cache is applied. Check out the {{#crossLink "Filter"}}{{/crossLink}}
	 * class for more information. Some filters (ex. BlurFilter) will not work as expected in conjunction with the scale param.
	 * 
	 * Usually, the resulting cacheCanvas will have the dimensions width*scale by height*scale, however some filters (ex. BlurFilter)
	 * will add padding to the canvas dimensions.
	 *
	 * @method cache
	 * @param {Number} x The x coordinate origin for the cache region.

	 * @param {Number} width The width of the cache region.
	 * @param {Number} height The height of the cache region.
	 * @param {Number} [scale=1] The scale at which the cache will be created. For example, if you cache a vector shape using
	 * 	myShape.cache(0,0,100,100,2) then the resulting cacheCanvas will be 200x200 px. This lets you scale and rotate

	 * The MovieClip class associates a TweenJS Timeline with an EaselJS {{#crossLink "Container"}}{{/crossLink}}. It allows

	 * complexities inherent in correctly setting up a MovieClip, it is largely intended for tool output and is not included
	 * in the main EaselJS library.
	 *
	 * Currently MovieClip only works properly if it is tick based (as opposed to time based) though some concessions have
	 * been made to support time-based timelines in the future.
	 *
	 * <h4>Example</h4>

	 * the animation using {{#crossLink "MovieClip/gotoAndPlay"}}{{/crossLink}}.

	/**
	 * The LoadQueue class is the main API for preloading content. LoadQueue is a load manager, which can preload either
	 * a single file, or queue of files.
	 *
	 * <b>Creating a Queue</b><br />
	 * To use LoadQueue, create a LoadQueue instance. If you want to force tag loading where possible, set the preferXHR
	 * argument to false.
	 *
	 *      var queue = new createjs.LoadQueue(true);
	 *
	 * <b>Listening for Events</b><br />
	 * Add any listeners you want to the queue. Since PreloadJS 0.3.0, the {{#crossLink "EventDispatcher"}}{{/crossLink}}
	 * lets you add as many listeners as you want for events. You can subscribe to the following events:<ul>
	 *     <li>{{#crossLink "AbstractLoader/complete:event"}}{{/crossLink}}: fired when a queue completes loading all
	 *     files</li>
	 *     <li>{{#crossLink "AbstractLoader/error:event"}}{{/crossLink}}: fired when the queue encounters an error with
	 *     any file.</li>
	 *     <li>{{#crossLink "AbstractLoader/progress:event"}}{{/crossLink}}: Progress for the entire queue has
	 *     changed.</li>
	 *     <li>{{#crossLink "LoadQueue/fileload:event"}}{{/crossLink}}: A single file has completed loading.</li>
	 *     <li>{{#crossLink "LoadQueue/fileprogress:event"}}{{/crossLink}}: Progress for a single file has changes. Note
	 *     that only files loaded with XHR (or possibly by plugins) will fire progress events other than 0 or 100%.</li>
	 * </ul>
	 *
	 *      queue.on("fileload", handleFileLoad, this);
	 *      queue.on("complete", handleComplete, this);
	 *
	 * <b>Adding files and manifests</b><br />
	 * Add files you want to load using {{#crossLink "LoadQueue/loadFile"}}{{/crossLink}} or add multiple files at a
	 * time using a list or a manifest definition using {{#crossLink "LoadQueue/loadManifest"}}{{/crossLink}}. Files are
	 * appended to the end of the active queue, so you can use these methods as many times as you like, whenever you
	 * like.
	 *
	 *      queue.loadFile("filePath/file.jpg");
	 *      queue.loadFile({id:"image", src:"filePath/file.jpg"});
	 *      queue.loadManifest(["filePath/file.jpg", {id:"image", src:"filePath/file.jpg"}]);
	 *
	 *      // Use an external manifest
	 *      queue.loadManifest("path/to/manifest.json");
	 *      queue.loadManifest({src:"manifest.json", type:"manifest"});
	 *
	 * If you pass `false` as the `loadNow` parameter, the queue will not kick of the load of the files, but it will not
	 * stop if it has already been started. Call the {{#crossLink "AbstractLoader/load"}}{{/crossLink}} method to begin
	 * a paused queue. Note that a paused queue will automatically resume when new files are added to it with a
	 * `loadNow` argument of `true`.
	 *
	 *      queue.load();
	 *
	 * <b>File Types</b><br />
	 * The file type of a manifest item is auto-determined by the file extension. The pattern matching in PreloadJS
	 * should handle the majority of standard file and url formats, and works with common file extensions. If you have
	 * either a non-standard file extension, or are serving the file using a proxy script, then you can pass in a
	 * <code>type</code> property with any manifest item.
	 *
	 *      queue.loadFile({src:"path/to/myFile.mp3x", type:createjs.AbstractLoader.SOUND});
	 *
	 *      // Note that PreloadJS will not read a file extension from the query string
	 *      queue.loadFile({src:"http://server.com/proxy?file=image.jpg", type:createjs.AbstractLoader.IMAGE});
	 *
	 * Supported types are defined on the {{#crossLink "AbstractLoader"}}{{/crossLink}} class, and include:
	 * <ul>
	 *     <li>{{#crossLink "AbstractLoader/BINARY:property"}}{{/crossLink}}: Raw binary data via XHR</li>
	 *     <li>{{#crossLink "AbstractLoader/CSS:property"}}{{/crossLink}}: CSS files</li>
	 *     <li>{{#crossLink "AbstractLoader/IMAGE:property"}}{{/crossLink}}: Common image formats</li>
	 *     <li>{{#crossLink "AbstractLoader/JAVASCRIPT:property"}}{{/crossLink}}: JavaScript files</li>
	 *     <li>{{#crossLink "AbstractLoader/JSON:property"}}{{/crossLink}}: JSON data</li>
	 *     <li>{{#crossLink "AbstractLoader/JSONP:property"}}{{/crossLink}}: JSON files cross-domain</li>
	 *     <li>{{#crossLink "AbstractLoader/MANIFEST:property"}}{{/crossLink}}: A list of files to load in JSON format, see
	 *     {{#crossLink "AbstractLoader/loadManifest"}}{{/crossLink}}</li>
	 *     <li>{{#crossLink "AbstractLoader/SOUND:property"}}{{/crossLink}}: Audio file formats</li>
	 *     <li>{{#crossLink "AbstractLoader/SPRITESHEET:property"}}{{/crossLink}}: JSON SpriteSheet definitions. This
	 *     will also load sub-images, and provide a {{#crossLink "SpriteSheet"}}{{/crossLink}} instance.</li>
	 *     <li>{{#crossLink "AbstractLoader/SVG:property"}}{{/crossLink}}: SVG files</li>
	 *     <li>{{#crossLink "AbstractLoader/TEXT:property"}}{{/crossLink}}: Text files - XHR only</li>
     *     <li>{{#crossLink "AbstractLoader/VIDEO:property"}}{{/crossLink}}: Video objects</li>
	 *     <li>{{#crossLink "AbstractLoader/XML:property"}}{{/crossLink}}: XML data</li>
	 * </ul>
	 *
	 * <em>Note: Loader types used to be defined on LoadQueue, but have been moved to AbstractLoader for better
	 * portability of loader classes, which can be used individually now. The properties on LoadQueue still exist, but
	 * are deprecated.</em>
	 *
	 * <b>Handling Results</b><br />
	 * When a file is finished downloading, a {{#crossLink "LoadQueue/fileload:event"}}{{/crossLink}} event is
	 * dispatched. In an example above, there is an event listener snippet for fileload. Loaded files are usually a
	 * formatted object that can be used immediately, including:
	 * <ul>
	 *     <li>Binary: The binary loaded result</li>
	 *     <li>CSS: A &lt;link /&gt; tag</li>
	 *     <li>Image: An &lt;img /&gt; tag</li>
	 *     <li>JavaScript: A &lt;script /&gt; tag</li>
	 *     <li>JSON/JSONP: A formatted JavaScript Object</li>
	 *     <li>Manifest: A JavaScript object.
	 *     <li>Sound: An &lt;audio /&gt; tag</a>
	 *     <li>SpriteSheet: A {{#crossLink "SpriteSheet"}}{{/crossLink}} instance, containing loaded images.
	 *     <li>SVG: An &lt;object /&gt; tag</li>
	 *     <li>Text: Raw text</li>
     *     <li>Video: A Video DOM node</li>
	 *     <li>XML: An XML DOM node</li>
	 * </ul>
	 *
	 *      function handleFileLoad(event) {
	 *          var item = event.item; // A reference to the item that was passed in to the LoadQueue
	 *          var type = item.type;
	 *
	 *          // Add any images to the page body.
	 *          if (type == createjs.LoadQueue.IMAGE) {
	 *              document.body.appendChild(event.result);
	 *          }
	 *      }
	 *
	 * At any time after the file has been loaded (usually after the queue has completed), any result can be looked up
	 * via its "id" using {{#crossLink "LoadQueue/getResult"}}{{/crossLink}}. If no id was provided, then the
	 * "src" or file path can be used instead, including the `path` defined by a manifest, but <strong>not including</strong>
	 * a base path defined on the LoadQueue. It is recommended to always pass an id if you want to look up content.
	 *
	 *      var image = queue.getResult("image");
	 *      document.body.appendChild(image);
	 *
	 * Raw loaded content can be accessed using the <code>rawResult</code> property of the {{#crossLink "LoadQueue/fileload:event"}}{{/crossLink}}
	 * event, or can be looked up using {{#crossLink "LoadQueue/getResult"}}{{/crossLink}}, passing `true` as the 2nd
	 * argument. This is only applicable for content that has been parsed for the browser, specifically: JavaScript,
	 * CSS, XML, SVG, and JSON objects, or anything loaded with XHR.
	 *
	 *      var image = queue.getResult("image", true); // load the binary image data loaded with XHR.
	 *
	 * <b>Plugins</b><br />
	 * LoadQueue has a simple plugin architecture to help process and preload content. For example, to preload audio,
	 * make sure to install the <a href="http://soundjs.com">SoundJS</a> Sound class, which will help load HTML audio,
	 * Flash audio, and WebAudio files. This should be installed <strong>before</strong> loading any audio files.
	 *
	 *      queue.installPlugin(createjs.Sound);
	 *
	 * <h4>Known Browser Issues</h4>
	 * <ul>

/**
 * <strong>Note: AudioSprite is not a class, but its usage is easily lost in the documentation, so it has been called
 * out here for quick reference.</strong>
 *
 * Audio sprites are much like CSS sprites or image sprite sheets: multiple audio assets grouped into a single file.
 * Audio sprites work around limitations in certain browsers, where only a single sound can be loaded and played at a
 * time. We recommend at least 300ms of silence between audio clips to deal with HTML audio tag inaccuracy, and to prevent
 * accidentally playing bits of the neighbouring clips.
 *
 * <strong>Benefits of Audio Sprites:</strong>
 * <ul>
 *     <li>More robust support for older browsers and devices that only allow a single audio instance, such as iOS 5.</li>
 *     <li>They provide a work around for the Internet Explorer 9 audio tag limit, which restricts how many different
 *     sounds that could be loaded at once.</li>
 *     <li>Faster loading by only requiring a single network request for several sounds, especially on mobile devices
 * where the network round trip for each file can add significant latency.</li>
 * </ul>
 *
 * <strong>Drawbacks of Audio Sprites</strong>
 * <ul>
 *     <li>No guarantee of smooth looping when using HTML or Flash audio. If you have a track that needs to loop
 * 		smoothly and you are supporting non-web audio browsers, do not use audio sprites for that sound if you can avoid
 * 		it.</li>
 *     <li>No guarantee that HTML audio will play back immediately, especially the first time. In some browsers
 *     (Chrome!), HTML audio will only load enough to play through at the current download speed – so we rely on the
 *     `canplaythrough` event to determine if the audio is loaded. Since audio sprites must jump ahead to play specific
 *     sounds, the audio may not yet have downloaded fully.</li>
 *     <li>Audio sprites share the same core source, so if you have a sprite with 5 sounds and are limited to 2
 * 		concurrently playing instances, you can only play 2 of the sounds at the same time.</li>
 * </ul>
 *
 * <h4>Example</h4>
 *
 *		createjs.Sound.initializeDefaultPlugins();
 *		var assetsPath = "./assets/";
 *		var sounds = [{
 *			src:"MyAudioSprite.ogg", data: {
 *				audioSprite: [
 *					{id:"sound1", startTime:0, duration:500},
 *					{id:"sound2", startTime:1000, duration:400},
 *					{id:"sound3", startTime:1700, duration: 1000}
 *				]}
 *			}
 *		];
 *		createjs.Sound.alternateExtensions = ["mp3"];
 *		createjs.Sound.on("fileload", loadSound);
 *		createjs.Sound.registerSounds(sounds, assetsPath);
 *		// after load is complete
 *		createjs.Sound.play("sound2");
 *
 * You can also create audio sprites on the fly by setting the startTime and duration when creating an new AbstractSoundInstance.
 *
 * 		createjs.Sound.play("MyAudioSprite", {startTime: 1000, duration: 400});
 *
 * The excellent CreateJS community has created a tool to create audio sprites, available at
 * <a href="https://github.com/tonistiigi/audiosprite" target="_blank">https://github.com/tonistiigi/audiosprite</a>,
 * as well as a <a href="http://jsfiddle.net/bharat_battu/g8fFP/12/" target="_blank">jsfiddle</a> to convert the output
 * to SoundJS format.

	/**
	 * The Sound class is the public API for creating sounds, controlling the overall sound levels, and managing plugins.
	 * All Sound APIs on this class are static.
	 *
	 * <b>Registering and Preloading</b><br />
	 * Before you can play a sound, it <b>must</b> be registered. You can do this with {{#crossLink "Sound/registerSound"}}{{/crossLink}},
	 * or register multiple sounds using {{#crossLink "Sound/registerSounds"}}{{/crossLink}}. If you don't register a
	 * sound prior to attempting to play it using {{#crossLink "Sound/play"}}{{/crossLink}} or create it using {{#crossLink "Sound/createInstance"}}{{/crossLink}},
	 * the sound source will be automatically registered but playback will fail as the source will not be ready. If you use
	 * <a href="http://preloadjs.com" target="_blank">PreloadJS</a>, registration is handled for you when the sound is
	 * preloaded. It is recommended to preload sounds either internally using the register functions or externally using
	 * PreloadJS so they are ready when you want to use them.
	 *
	 * <b>Playback</b><br />
	 * To play a sound once it's been registered and preloaded, use the {{#crossLink "Sound/play"}}{{/crossLink}} method.
	 * This method returns a {{#crossLink "AbstractSoundInstance"}}{{/crossLink}} which can be paused, resumed, muted, etc.
	 * Please see the {{#crossLink "AbstractSoundInstance"}}{{/crossLink}} documentation for more on the instance control APIs.
	 *
	 * <b>Plugins</b><br />
	 * By default, the {{#crossLink "WebAudioPlugin"}}{{/crossLink}} or the {{#crossLink "HTMLAudioPlugin"}}{{/crossLink}}
	 * are used (when available), although developers can change plugin priority or add new plugins (such as the
	 * provided {{#crossLink "FlashAudioPlugin"}}{{/crossLink}}). Please see the {{#crossLink "Sound"}}{{/crossLink}} API
	 * methods for more on the playback and plugin APIs. To install plugins, or specify a different plugin order, see
	 * {{#crossLink "Sound/installPlugins"}}{{/crossLink}}.
	 *
	 * <h4>Example</h4>
	 *
	 *      createjs.FlashAudioPlugin.swfPath = "../src/soundjs/flashaudio";
	 *      createjs.Sound.registerPlugins([createjs.WebAudioPlugin, createjs.FlashAudioPlugin]);
	 *      createjs.Sound.alternateExtensions = ["mp3"];
	 *      createjs.Sound.on("fileload", this.loadHandler, this);
	 *      createjs.Sound.registerSound("path/to/mySound.ogg", "sound");
	 *      function loadHandler(event) {
     *          // This is fired for each sound that is registered.
     *          var instance = createjs.Sound.play("sound");  // play using id.  Could also use full source path or event.src.
     *          instance.on("complete", this.handleComplete, this);
     *          instance.volume = 0.5;
	 *      }
	 *
	 * The maximum number of concurrently playing instances of the same sound can be specified in the "data" argument
	 * of {{#crossLink "Sound/registerSound"}}{{/crossLink}}.  Note that if not specified, the active plugin will apply
	 * a default limit.  Currently HTMLAudioPlugin sets a default limit of 2, while WebAudioPlugin and FlashAudioPlugin set a
	 * default limit of 100.
	 *
	 *      createjs.Sound.registerSound("sound.mp3", "soundId", 4);
	 *
	 * Sound can be used as a plugin with PreloadJS to help preload audio properly. Audio preloaded with PreloadJS is
	 * automatically registered with the Sound class. When audio is not preloaded, Sound will do an automatic internal
	 * load. As a result, it may fail to play the first time play is called if the audio is not finished loading. Use
	 * the {{#crossLink "Sound/fileload:event"}}{{/crossLink}} event to determine when a sound has finished internally
	 * preloading. It is recommended that all audio is preloaded before it is played.
	 *
	 *      var queue = new createjs.LoadQueue();
	 *		queue.installPlugin(createjs.Sound);
	 *
	 * <b>Audio Sprites</b><br />
	 * SoundJS has added support for {{#crossLink "AudioSprite"}}{{/crossLink}}, available as of version 0.6.0.
	 * For those unfamiliar with audio sprites, they are much like CSS sprites or sprite sheets: multiple audio assets
	 * grouped into a single file.

	 * <h4>Example</h4>
	 *
	 *		var assetsPath = "./assets/";

	 *					{id:"sound2", startTime:1000, duration:400},

	 *		createjs.Sound.alternateExtensions = ["mp3"];

	 *		createjs.Sound.registerSounds(sounds, assetsPath);
	 *		// after load is complete
	 *		createjs.Sound.play("sound2");
	 *
	 * <b>Mobile Playback</b><br />
	 * Devices running iOS require the WebAudio context to be "unlocked" by playing at least one sound inside of a user-
	 * initiated event (such as touch/click). Earlier versions of SoundJS included a "MobileSafe" sample, but this is no
	 * longer necessary as of SoundJS 0.6.2.

	 *         In SoundJS 0.4.1 and above, you can either initialize plugins or use the {{#crossLink "WebAudioPlugin/playEmptySound"}}{{/crossLink}}
	 *         method in the call stack of a user input event to manually unlock the audio context.
	 *     </li>
	 *     <li>
	 *         In SoundJS 0.6.2 and above, SoundJS will automatically listen for the first document-level "mousedown"
	 *         and "touchend" event, and unlock WebAudio. This will continue to check these events until the WebAudio
	 *         context becomes "unlocked" (changes from "suspended" to "running")
	 *     </li>
	 *     <li>
	 *         Both the "mousedown" and "touchend" events can be used to unlock audio in iOS9+, the "touchstart" event
	 *         will work in iOS8 and below. The "touchend" event will only work in iOS9 when the gesture is interpreted
	 *         as a "click", so if the user long-presses the button, it will no longer work.
	 *     </li>
	 *     <li>
	 *         When using the <a href="http://www.createjs.com/docs/easeljs/classes/Touch.html">EaselJS Touch class</a>,
	 *         the "mousedown" event will not fire when a canvas is clicked, since MouseEvents are prevented, to ensure
	 *         only touch events fire. To get around this, you can either rely on "touchend", or:
	 *         <ol>
	 *             <li>Set the `allowDefault` property on the Touch class constructor to `true` (defaults to `false`).</li>
	 *             <li>Set the `preventSelection` property on the EaselJS `Stage` to `false`.</li>
	 *         </ol>
	 *         These settings may change how your application behaves, and are not recommended.
	 *     </li>
	 * </ul>
	 *
	 * <b>Loading Alternate Paths and Extension-less Files</b><br />
	 * SoundJS supports loading alternate paths and extension-less files by passing an object instead of a string for
	 * the `src` property, which is a hash using the format `{extension:"path", extension2:"path2"}`. These labels are
	 * how SoundJS determines if the browser will support the sound. This also enables multiple formats to live in
	 * different folders, or on CDNs, which often has completely different filenames for each file.
	 *
	 * Priority is determined by the property order (first property is tried first).  This is supported by both internal loading
	 * and loading with PreloadJS.
	 *
	 * <em>Note: an id is required for playback.</em>
	 *
	 * <h4>Example</h4>
	 *
	 *		var sounds = {path:"./audioPath/",
	 * 				manifest: [
	 *				{id: "cool", src: {mp3:"mp3/awesome.mp3", ogg:"noExtensionOggFile"}}
	 *		]};
	 *
	 *		createjs.Sound.alternateExtensions = ["mp3"];
	 *		createjs.Sound.addEventListener("fileload", handleLoad);
	 *		createjs.Sound.registerSounds(sounds);
	 *
	 * <h3>Known Browser and OS issues</h3>
	 * <b>IE 9 HTML Audio limitations</b><br />
	 * <ul><li>There is a delay in applying volume changes to tags that occurs once playback is started. So if you have
	 * muted all sounds, they will all play during this delay until the mute applies internally. This happens regardless of
	 * when or how you apply the volume change, as the tag seems to need to play to apply it.</li>
     * <li>MP3 encoding will not always work for audio tags, particularly in Internet Explorer. We've found default
	 * encoding with 64kbps works.</li>
	 * <li>Occasionally very short samples will get cut off.</li>
	 * <li>There is a limit to how many audio tags you can load and play at once, which appears to be determined by
	 * hardware and browser settings.  See {{#crossLink "HTMLAudioPlugin.MAX_INSTANCES"}}{{/crossLink}} for a safe
	 * estimate.</li></ul>
	 *
	 * <b>Firefox 25 Web Audio limitations</b>
	 * <ul><li>mp3 audio files do not load properly on all windows machines, reported
	 * <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=929969" target="_blank">here</a>. </br>
	 * For this reason it is recommended to pass another FF supported type (ie ogg) first until this bug is resolved, if
	 * possible.</li></ul>

	 * <b>Safari limitations</b><br />
	 * <ul><li>Safari requires Quicktime to be installed for audio playback.</li></ul>
	 *
	 * <b>iOS 6 Web Audio limitations</b><br />
	 * <ul><li>Sound is initially locked, and must be unlocked via a user-initiated event. Please see the section on
	 * Mobile Playback above.</li>
	 * <li>A bug exists that will distort un-cached web audio when a video element is present in the DOM that has audio
	 * at a different sampleRate.</li>
	 * </ul>
	 *
	 * <b>Android HTML Audio limitations</b><br />
	 * <ul><li>We have no control over audio volume. Only the user can set volume on their device.</li>
	 * <li>We can only play audio inside a user event (touch/click).  This currently means you cannot loop sound or use
	 * a delay.</li></ul>
	 *
	 * <b>Web Audio and PreloadJS</b><br />
	 * <ul><li>Web Audio must be loaded through XHR, therefore when used with PreloadJS, tag loading is not possible.
	 * This means that tag loading can not be used to avoid cross domain issues.</li><ul>

	/**
	 * Play an instance. This method is intended to be called on SoundInstances that already exist (created
	 * with the Sound API {{#crossLink "Sound/createInstance"}}{{/crossLink}} or {{#crossLink "Sound/play"}}{{/crossLink}}).
	 *
	 * <h4>Example</h4>
	 *
	 *      var myInstance = createjs.Sound.createInstance(mySrc);
	 *      myInstance.play({interrupt:createjs.Sound.INTERRUPT_ANY, loop:2, pan:0.5});
	 *
	 * Note that if this sound is already playing, this call will still set the passed in parameters.

	 * <b>Parameters Deprecated</b><br />
	 * The parameters for this method are deprecated in favor of a single parameter that is an Object or {{#crossLink "PlayPropsConfig"}}{{/crossLink}}.
	 *
	 * @method play
	 * @param {String | Object} [interrupt="none"|options] <b>This parameter will be renamed playProps in the next release.</b><br />
	 * This parameter can be an instance of {{#crossLink "PlayPropsConfig"}}{{/crossLink}} or an Object that contains any or all optional properties by name,
	 * including: interrupt, delay, offset, loop, volume, pan, startTime, and duration (see the above code sample).
	 * <br /><strong>OR</strong><br />
	 * <b>Deprecated</b> How to interrupt any currently playing instances of audio with the same source,
	 * if the maximum number of instances of the sound are already playing. Values are defined as <code>INTERRUPT_TYPE</code>
	 * constants on the Sound class, with the default defined by {{#crossLink "Sound/defaultInterruptBehavior:property"}}{{/crossLink}}.
	 * @param {Number} [delay=0] <b>Deprecated</b> The amount of time to delay the start of audio playback, in milliseconds.
	 * @param {Number} [offset=0] <b>Deprecated</b> The offset from the start of the audio to begin playback, in milliseconds.
	 * @param {Number} [loop=0] <b>Deprecated</b> How many times the audio loops when it reaches the end of playback. The default is 0 (no
	 * loops), and -1 can be used for infinite playback.
	 * @param {Number} [volume=1] <b>Deprecated</b> The volume of the sound, between 0 and 1. Note that the master volume is applied
	 * against the individual volume.
	 * @param {Number} [pan=0] <b>Deprecated</b> The left-right pan of the sound (if supported), between -1 (left) and 1 (right).
	 * Note that pan is not supported for HTML Audio.
	 * @return {AbstractSoundInstance} A reference to itself, intended for chaining calls.

	 * Play sounds using HTML &lt;audio&gt; tags in the browser. This plugin is the second priority plugin installed

	 * audio, include and install the {{#crossLink "FlashAudioPlugin"}}{{/crossLink}}.
	 *
	 * <h4>Known Browser and OS issues for HTML Audio</h4>
	 * <b>All browsers</b><br />
	 * Testing has shown in all browsers there is a limit to how many audio tag instances you are allowed.  If you exceed
	 * this limit, you can expect to see unpredictable results. Please use {{#crossLink "Sound.MAX_INSTANCES"}}{{/crossLink}} as
	 * a guide to how many total audio tags you can safely use in all browsers.  This issue is primarily limited to IE9.
	 *
     * <b>IE html limitations</b><br />
     * <ul><li>There is a delay in applying volume changes to tags that occurs once playback is started. So if you have
     * muted all sounds, they will all play during this delay until the mute applies internally. This happens regardless of
     * when or how you apply the volume change, as the tag seems to need to play to apply it.</li>
     * <li>MP3 encoding will not always work for audio tags if it's not default.  We've found default encoding with
     * 64kbps works.</li>
	 * <li>Occasionally very short samples will get cut off.</li>
	 * <li>There is a limit to how many audio tags you can load or play at once, which appears to be determined by
	 * hardware and browser settings.  See {{#crossLink "HTMLAudioPlugin.MAX_INSTANCES"}}{{/crossLink}} for a safe estimate.
	 * Note that audio sprites can be used as a solution to this issue.</li></ul>
	 *
	 * <b>Safari limitations</b><br />
	 * <ul><li>Safari requires Quicktime to be installed for audio playback.</li></ul>
	 *
	 * <b>iOS 6 limitations</b><br />
	 * <ul><li>can only have one &lt;audio&gt; tag</li>
	 * 		<li>can not preload or autoplay the audio</li>
	 * 		<li>can not cache the audio</li>
	 * 		<li>can not play the audio except inside a user initiated event.</li>
	 *		<li>Note it is recommended to use {{#crossLink "WebAudioPlugin"}}{{/crossLink}} for iOS (6+)</li>
	 * 		<li>audio sprites can be used to mitigate some of these issues and are strongly recommended on iOS</li>
	 * </ul>
	 *
	 * <b>Android Native Browser limitations</b><br />
	 * <ul><li>We have no control over audio volume. Only the user can set volume on their device.</li>
	 *      <li>We can only play audio inside a user event (touch/click).  This currently means you cannot loop sound or use a delay.</li></ul>
	 * <b> Android Chrome 26.0.1410.58 specific limitations</b><br />
	 * <ul> <li>Can only play 1 sound at a time.</li>

	 *      <LI> end: Optional, 0-1 : Final position, default 1 if not specified.</LI>
	 *      <LI> orient: Optional, string : "fixed"/"auto"/"cw"/"ccw"<UL>
	 *				<LI>"fixed" forces the object to face down the path all movement (relative to start rotation),</LI>
	 *      		<LI>"auto" rotates the object along the path relative to the line.</LI>
	 *      		<LI>"cw"/"ccw" force clockwise or counter clockwise rotations including flash like behaviour</LI>
